Do anyone want to test their grip strength? Like small hand wrestling with ourselves? This Hand Grip Strength Tester Circuit is a hand grip tester. It uses simple electronic parts to check how hard we can squeeze. More squeeze then more lights turn ON which shows our grip power. Circuit Working: Parts List: Component Value/Type […]

Simple Transistor Tester Circuit
Transistors are small switches. But how to check if they work or what type they are? This Simple Transistor Tester Circuit is like a transistor checker. It is an easy DIY project which uses few parts. It tells us if transistor is good or bad and also shows if its NPN or PNP like two […]
Simple Micro Ampere Meter Circuit
Simple Micro Ampere Meter Circuit is like a special tool to measure small electric. Normal tools too are strong but are not good for tiny current. But this one uses super sensitive meter microammeter or maybe special setting on multimeter to find very small electric flow like millionth of amp. Other parts like resistors and […]
Simple Electronic Component Tester Circuit
This Simple Electronic Component Tester Circuit works like doctor for ones electronic parts. Before we make any cool thing one can use this tester to check parts like resistor, capacitor, transistor and many more. Tester shows if the parts are good or bad so we do not waste time with broken parts in our project. […]
Wireless RF Network Cable Tester Circuit
Wireless RF Network Cable Tester Circuit is like X-ray for internet wire. It can catch radio signal inside cable like ethernet, modem or satellite TV but there is no need to touch the wire. It is very easy to use for checking cable working or not. Just hold tester near the wire and it will […]
Simple Temperature Meter Circuit
Simple Temperature Meter Circuit is like small detective for heat. It use special sensor like thermocouple or thermistor to feel heat near it. Sensor can be small part or smart chip like LM35 or LM34 which change heat into electric signal. Then circuit take this signal and confirms how much hot or cold it is. […]
